The 36V 50Ah TM Bluetooth LiFePO4 Battery with low-temperature protection and a built-in 50A BMS is engineered for demanding deep-cycle applications. It combines lithium iron phosphate chemistry for safety, Bluetooth for real-time monitoring, and cold-weather resilience (-20°C to 60°C). Ideal for RVs, marine systems, and solar storage, it offers 3,500+ cycles at 80% depth of discharge for long-term reliability.
How Does the Built-In 50A BMS Enhance Performance and Safety?
The 50A Battery Management System (BMS) ensures balanced cell charging, overvoltage/undervoltage protection, and thermal stability. It prevents short circuits, overcurrent, and overheating while optimizing energy flow. The BMS also enables low-temperature charging lockouts below -20°C, preserving cycle life. This extends the battery’s lifespan by up to 8 years under typical usage conditions.
The BMS actively monitors individual cell voltages, correcting imbalances during charging to prevent capacity fade. For example, if one cell reaches 3.65V before others during absorption, the BMS redirects current to undercharged cells. This precision extends cycle life by 18-22% compared to basic BMS designs. The system also features redundant MOSFET protection, capable of interrupting 200A surges within 2 milliseconds—critical for marine applications with unpredictable load spikes.

What Applications Benefit Most From This Battery?
Solar energy storage, trolling motors, electric forklifts, and telecom backup systems benefit from its 3,500-cycle lifespan. High discharge rates (50A continuous, 150A peak) support power-hungry devices like inverters. The vibration-resistant casing suits off-road vehicles, while IP65 rating protects against marine humidity.
In solar installations, the battery’s 98% round-trip efficiency minimizes energy loss compared to 80-85% in lead-acid systems. For trolling motors, the flat discharge curve maintains consistent thrust even at 20% SOC. Telecom towers leverage the Bluetooth BMS to schedule maintenance via SOC trends rather than fixed intervals, reducing site visits by 40%. Electric forklifts benefit from rapid 2-hour charging, enabling 3-shift operations without battery swaps.

Expert Views
“This battery’s low-temperature tech bridges a major gap in lithium adoption,” says a renewable energy engineer. “Most LiFePO4 cells can’t charge below freezing without degradation. The self-heating BMS and -20°C tolerance let users deploy it in climates like Alaska or Nordic regions—previously unthinkable without expensive external heaters.”
Conclusion
The 36V 50Ah TM LiFePO4 Battery redefines deep-cycle performance with Bluetooth diagnostics, cold-weather resilience, and a robust BMS. Its Group31 footprint and 50A discharge meet industrial and recreational demands, offering 8-10 years of service with minimal maintenance—ideal for users prioritizing longevity over upfront cost.
FAQs
- Can this battery replace two 12V lead-acid batteries in series?
- Yes—its 36V output matches 3x12V lead-acid in series. Ensure your charger supports LiFePO4 voltage profiles.
- Does Bluetooth drain the battery?
- The BMS uses <0.3mA in standby—less than 1% annual self-discharge. No impact on runtime.
- Is external heating required at -20°C?
- No—the BMS auto-activates internal heating. External insulation is recommended for extreme cold.
